I’m trying to build documentation for a package I’m developing using Documenter.jl, but I currently got stuck getting  
`Warning: unable to get the binding for 'readMDTable(file::String; header::Bool=true)::DataFrame' in `@docs` block in src\index.md from expression ':(readMDTable(file::String; header::Bool = true)::DataFrame)' in module MDTables │ `@docs  
│ readMDTable(file::String; header::Bool=true)::DataFrame  
│ writeMDTable(fileName::String, df)  
│ ` │ exception = `binding` cannot understand expression `readMDTable(file::String; header::Bool = true)::DataFrame`.`

Tought maybe the documentation for that specific function wasn’t loaded correctly but when looking for the documentation in the REPL it does finds it.

```julia
help?> readMDTable
search: readMDTable

  readMDTable(file::String; header::Bool=true)::DataFrame

  Reads into a DataFrame any MD table file. It's assumed the file will have a header, but can be specified with header=false if there isn't one.

```

Any help would be appreciated.

Remove `::DataFrame` from the end of that line inside your `@docs` block in your docs?

Thanks, it seems like that was the problem.
